Subject: [PATCH] mfd: ABX500_CORE should depend on ARCH_U8500

The ST-Ericsson ABX500 Mixed Signal IC family chips are only present on
ST-Ericsson U8500 Series platforms.  Hence add a dependency on
ARCH_U8500, to prevent asking the user about this driver when
configuring a kernel without U8500 support.

Also, merely enabling CONFIG_COMPILE_TEST should not enable additional
code, and thus should not enable this driver by default.

 	  Say yes here if you have the ABX500 Mixed Signal IC family
 	  chips. This core driver expose register access functions.
